[AMDGPU] Add volatile support to SIMemoryLegalizer

Treat a non-atomic volatile load and store as a relaxed atomic at
system scope for the address spaces accessed. This will ensure all
relevant caches will be bypassed.

A volatile atomic is not changed and still only bypasses caches upto
the level specified by the SyncScope operand.

AMDGPU: Increase branch size estimate with offset bug

This will be relaxed to insert a nop if the offset hits the bad value,
so over estimate branch instruction sizes.
